Abstract

1. A weighing apparatus for determining the mass throughput in the inlet of an extruder, comprising : a first container which can be filled with the material to be extruded and has a weighing device ; and evaluating apparatus for the measured values supplied by the weighing device ; and a more particularly funnel-shaped container which is disposed upstream of the extruder inlet and is open in the direction thereof and into which the contents of the first container can be emptied in batches, characterized in that the tank (13) open in the direction of the inlet (2) is freely suspended from or borne on a weighing device (12) and is connected to the inlet (2) exclusively via the flow of material, and the evaluating apparatus (14) converts the continuously collected measured values supplied by the weighing device (12) and the relative mass throughput determined by differentiation of such measured values into the absolute mass throughput, by equating the measured value for the absolute weight of the material, obtained on each emptying from the weighing device (10) of the first container (7), with the change (difference) in the measured values delivered by the weighing device (12) of the container (11) open in the direction of the inlet (2).
